A case is described of multiple currentsheets crossed by the MAGION-2 satellite in the near-midnight quieting auroraloval. The data were obtained by the magnetometer experiment onboard. Resultsshow during a quieting period after a preceding substorm, or during an earlygrowth phase of the next substorm, two double-sheet current bands, POLB and EQUB,located at respectively the polar and equatorial borders of the auroral ovalseparated by about 500 km in latitude. This is consistent with the double-ovalstructure during recovery introduced by Elphinstone <i>et al</i>. (1995). Withinthe POLB, the magnetic field data show simultaneous existence of several narrowparallel bipolar current sheets within the upward current branch (at 69.5–70.3°invariant latitude) with an adjacent downward current branch at its polar sideat (70.5–71.3°). The EQUB was similarly stratified and located at 61.2–63.5°invariant latitude. The narrow current sheets were separated on average by about35 km and 15 km, respectively, within the POLB and EQUB. A similar case ofdouble-oval current bands with small-scale structuring of their upward currentbranches during a quieting period is found in the data from the MAGION-3satellite. These observations contribute to the double-oval structure of thelate recovery phase, and add a small-scale structuring of the upward currentsproducing the auroral arcs in the double- oval pattern, at least for the casespresented here. Other observations of multiple auroral current sheets andtheories of auroral arc multiplicity are briefly discussed. It is suggested thatmultiple X-lines in the distant tail, and/or leakage of energetic particles andFA currents from a series of plasmoids formed during preceding magneticactivity, could be one cause of highly stratified upward FA currents at thepolar edge of the quieting double auroral oval
